Sinister 2 (2015)

Dylan Collins awakens from a nightmare in which a family of three are killed in a cornfield. Dylan, his twin brother, Zach, and their mother, Courtney, squat in a farmhouse after running away from Courtney's abusive husband, Clint. In addition to having nightmares of families being murdered, Dylan is visited by ghostly children who coerce him into watching films of the children murdering their families.

Former sheriff's deputy "So-and-so", now a private investigator, investigates the murders connected to Bughuul. He arrives at the farmhouse and finds the Collins family. He tells Courtney that he is there to investigate the church where a murder took place. So-and-so drives away Clint, who tries to take the boys, and convinces Courtney to stay at the farmhouse, knowing that leaving will continue Bughuul's murders. Courtney invites him to spend the night.

So-and-so meets with Professor Stromberg, the owner of a ham radio that belonged to Professor Jonas, who mysteriously disappeared. Stromberg tells So-and-so that the radio belonged to a Norwegian family that was murdered in 1973. He tells So-and-so that Bughuul is invited through ritual sacrifice, with three common traits present: a murdered family, missing children, and artwork of Bughuul. After the radio suddenly activates, the Deputy orders Stromberg to destroy it.

Zach acts violently toward Dylan, jealous of the ghost children's attentiveness to him. However, the children turn their attention toward him after Dylan refuses to watch another family being murdered, stating that Dylan is not their real target. Clint arrives with a court order and takes Courtney and the boys home. So-and-so arrives at their house to warn them about Bughuul, but Clint beats him. The next day, Zach films his family relaxing outdoors and spikes their drinks. That night, Dylan contacts the Deputy for help as he and his parents lose consciousness.

Courtney, Dylan, and Clint are hung on scarecrow posts with sacks over their heads, mirroring Dylan's nightmare. Zach douses them in gasoline, filming Clint burning to death. Before Zach can set Dylan on fire, So-and-so hits Zach with his car. He frees Courtney and Dylan, and they flee. Zach pursues and catches So-and-so, amputating a few of his fingers with a sickle. Inside the home, the ghost children help Zach locate Courtney and Dylan. Before he can kill them, So-and-so destroys the camera, making it impossible for Zach to complete the ritual. Zach frantically looks for another camera in the film trunk, but finds none. A disappointed Bughuul appears and kills Zach with a deathly touch as punishment for failing. Zach's body decays and bursts into flames, setting the house on fire. So-and-so, Dylan, and Courtney escape the house and watch it burn.

Later, while collecting his things to leave with Courtney and Dylan, the Deputy finds the ham radio in his motel room. The ghost children begin speaking to him through it before Bughuul suddenly appears.
